High-Voltage GaAs Photovoltaic Laser Power Converters

IEEE Transactions on Electron Devices, 2009
The main drawback of photovoltaic (PV) laser power converters based on GaAs material is the low output voltage, which is often insufficient to power electronic circuits directly. Aside from the use of a dc-dc converter in combination with a single PV converter, it is possible to boost the voltage by the monolithic serial interconnection of several ...

On the alignment tolerance of photovoltaic laser power converters

Optik, 2017
Abstract This work addresses the alignment of a light spot onto photovoltaic laser power converters for power-by-light applications. A model to compare the alignment tolerances of different cell designs by means of the maximum acceptable misalignment is introduced. Monolithic interconnected multi-segment cells, which are commonly used as high-voltage

GaAs converters for high power densities of laser illumination

Progress in Photovoltaics: Research and Applications, 2008
AbstractPhotovoltaic power converters can be used to generate electricity directly from laser light. In this paper we report the development of GaAs PV power converters with improved conversion efficiency at high power densities. The incorporation of a lateral conduction layer (LCL) on top of the window layer resulted in a considerable gain in ...
